Problems solved by technology

At present, there are few domestic reports on the artificial reproduction of S. chinensis. Only the sexual dimorphism of the morphological characteristics of S. chinensis during the reproductive period and the determination of female adult fertility and the selection of the size of river mussels during spawning and the cultivation of ornamental fish have been reported. Exploring the trial breeding of Selina sinensis in the aquarium, but failed to form a large-scale production

Embodiment 1

[0026] (1) Spawning pool

[0027] The spawning pond is an earthen pond with an area of ​​667 m 2 , the water depth is 1.3m, and the thickness of the bottom silt does not exceed 10cm. Spray and disinfect the whole pond with 100kg of quickliming slurry, inject water after 10 days, plant Elodea, and use 120kg of biological fertilizer to fertilize the water.

[0028] (2) Incubation pool

[0029] The hatching pool is a circular cement pool with a diameter of 1.2m, which has been sterilized by potassium permanganate in advance, and a circle of nano-microporous pipeline oxygenation equipment is laid on the bottom of the pool, and the water depth is 120cm.

[0030] 2. Selection and breeding of broodstock

[0031] The Chinese bream was caught in Nanyi Lake, Xuancheng City, Anhui Province, and the brood fish were selected as brood fish over 1 year old, with female fish weighing 1.2g-2.0g and male fish weighing 1.5g-4.0g, with good gonad maturity and strong physique. The scales are co...

Embodiment 2

[0055] (1) Spawning pool

[0056] The spawning pond is an earthen pond with an area of ​​1000 m 2 , the water depth is 1.5m, the thickness of the bottom silt is 8-9cm, and 150kg of quickliming slurry is splashed and disinfected in the whole pool, water is injected after 7 days, and Elodea and hornwort are planted, every 667 m 2 Fertilize water with 120kg biological fertilizer.

[0057] (2) Incubation pool

[0058]The hatching pool is a circular cement pool with a radius of 1.0m, which is sterilized with 2ppm potassium permanganate, and a circle of nano-microporous pipeline oxygenation equipment is laid on the bottom of the pool, and the water depth is 120cm.

[0059] 2. Broodstock selection

[0060] The broodstock should be more than 1 year old, the weight of female fish is 1.2g-2.0g, the weight of male fish is 1.5g-4.0g, the maturity of gonads is good, and the natural waters with strong physique are caught in natural waters. Before stocking, use 3% to 5% Soak in salt wate...

Embodiment 3

[0073] (1) Spawning pool

[0074] The spawning pond is an earthen pond with an area of ​​1330 m 2 , the water depth is 1.2m, the thickness of the bottom silt is 8-9cm, and 150kg of quickliming slurry is splashed and disinfected in the whole pool, water is injected after 9 days, and Elodea and hornwort are planted, every 667 m 2 Fertilize water with 150kg biological fertilizer.

[0075] (2) Incubation pool

[0076] The hatching pool is a circular cement pool with a radius of 2m, sterilized with 2ppm potassium permanganate, and a circle of nano-microporous pipeline oxygenation equipment is laid on the bottom of the pool, and the water depth is 80cm.

[0077] 2. Broodstock selection

[0078] The broodstock should be more than 1 year old, the weight of female fish is 1.2g-2.0g, the weight of male fish is 1.5g-4.0g, the maturity of gonads is good, and the natural waters with strong physique are caught in natural waters. Before stocking, use 3% to 5% Soak in salt water for 5 min...

Abstract

The invention discloses a rhodeus sinensis artificial propagation method. The method includes the steps that clams are used as hosts and put in plastic baskets, the plastic baskets are suspended on the peripheries of spawning ponds, and 1200-1600 clams are placed in each spawning pond; male and female parent fishes are paired according to the proportion of 1.1:1, and 1000-1200 pairs of parent fishes are put in each spawning pond; the clams with attached fertilized ova are suspended in the spawning ponds for conducting incubation in running water, and the incubation water temperature ranges from 26 DEG C to 30 DEG C. Through the method, the natural propagation process of rhodeus sinensis in a natural water environment is simulated to carry out manual pond propagation; the natural propagation environment of the rhodeus sinensis is created in the ponds, and the male and female parent fishes can conduct natural mating in the ponds, so that the survival rate of the parent fishes is increased; appropriate spawning hosts are selected, and the placement positions and modes of the hosts are reasonably adjusted, so that the propagation efficiency is effectively improved, and large-scale propagation of rhodeus sinensis fingerlings is achieved.

Description

technical field [0001] The invention relates to an artificial propagation method for scallop chinensis, belonging to the technical field of freshwater fish reproduction. Background technique [0002] Rhodeus sinensis, commonly known as Rhodeus sinensis, is a small bottom-dwelling fish belonging to Cyprinidae (Cyprinidae) subfamily (Acheilognathinae). It is widely distributed in the Yangtze River, Pearl River, Qiantang River and Minjiang River in the south of my country. And other water systems, mostly live in the still water area of ​​lakes and river ditches. It is not only the natural bait for large fish and birds, but also has ornamental value. Because of the very special reproductive habits of the bream: in the breeding season, the female fish uses the extended oviposition tube to lay eggs in the gill cavity of the mussel, and the fertilized eggs hatch in the gill cavity of the mussel, and when they develop to the point where they can swim, they can swim. out of the body ...
